Latewood, to be honest I never let it get past 1800ppm anymore because I do not see a difference in 1800 and 2000 and why use more nutrients...but the plant took it with no burn and a GREAT yield. It was however very large. You must also remember that 200 of that is my water so the amount of nutrients is not as much as it seems at first glance. Anyways, after this next grow I am working with Blueberry and Grapefruit and I can promise you I will be doing much much lower EC numbers. I have found our White Widow to be incredibly strong and hungry, but I am positive the lower yielding Grape and Blue will not eat nearly as much. That will be nice because right now we spend over $200 in nutrients per complete cycle, just for the one hydro room. And we get an awesome deal on the stuff. Thats almost 2.5 gallons of Micro, 2.5 gallons of bloom, and around 1.5 gallons of grow. If we are using Big Bud (which I like and is the only additive I use besides Hygrozyme) then its another $100 a grow for a gallon. $100 in Hygrozyme per complete cycle as well. Finally we have pH up and pH down (now this is one place I will argue to to the tooth, but AN has a far more concentrated pH then GH. It takes 5 drops to lower our 20 gallon reservoir by over a half point. It takes a tablespoon of GH pH down to do the same. I havent found a difference in holding the pH). pH up and down is another $20. So every complete cycle on one room, we are spending $420-$450 on nutrients. If I can get rid of the Bug Bud and run a lower PPM/EC and get the exact same results...well then I am freaking sold Latewood cause that could save me a couple hundred dollars a cycle which is 4 times a year so thats like nearly $1000 I could a year.

I guess I am simple in that I see the obvious visual correlation between gigantic huge healthy plants and large amounts of nutrients. I am worried about not using enough nutrients and feeling like I should have added more and I wasted time because I didnt. Know that feeling? If only I could get another grow of White Widow and try lower EC levels and compare.

PS. I have never found any of those small expensive AN additives to do jackshit but spend my cash; except Growth Excel. Have you used Growth Excel Latwood? If you have not, then that is the #1 thing you need to use (unless you use something that is of course very similar, it is a seawood extract foliar spray). Spray every morning when the lights come on. Results are fantastic. I dont use it on my hydro because the growth rate is too uncontrollable, but on our soil grows it works absolute wonders.
Racerx Reviewed by Racerx on . Latewood's Legacy: GH 3-part and CalMag tutorial and discussion After experimenting for 2 years with Advanced Nutrients/additives... Botanicare Pure blend Pro/additives...and GH3-part/additives. I fond this formula works and yields the best; And leaves the roots healthy throughout grow. Goodluck This should answer a lot of question's you newb's have, and It should save you some money in the longrun. Since a lot of you get caught up in the Lucas Method. I found this to yield more. However if you have space limitations, just remove the Grow from Rating: 5
